Subject: LU-498 pass oap instead of cookie to osc_teardown_async_page/osc_queue_async_io
X-Git-Tag: 2.0.66.0~15
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=8d1508dc531ae166346c3084604855069f30c117;hp=c0f12e41fbe766785ea0f6bb2db3a4801a4f3ff5

LU-498 pass oap instead of cookie to osc_teardown_async_page/osc_queue_async_io

Now that queue_async_io & teardown_async_page are not obd operations any
more, we don't need to use a cookie and can just pass the correct type.
